This machine tool is specially used for processing deep hole workpieces. It mainly uses the BTA method to process small diameter deep hole parts, and is particularly suitable for processing oil drill collars. The biggest structural feature of this machine tool is that the front side of the workpiece, close to the oiler end, is clamped by a double chuck, and the back side is clamped by a ring center frame.
